Showing favourites first when searching in mobile app before typing anyting in the search box solves the problem of frequently accessing app or site which BitWarden can’t recognise. E.g. I’ve noticed that if you have to fill-in a password for a regular http auth (the pop-up window) BitWarden never suggest the correct entry and if you frequently visit this site it is inconvenient to search it every time. That way the favourites would be useful in one more way.
